I have just changed a blown fuse for the heater control. The warm fan button now clicks and you can hear a click under the dash but fan not coming on. Any ideas anyone? The fuse was burnt out. It was working yesterday I think as had to sit in some traffic so put it on for 2 mins.
Check Heater control unit for burnt power connection terminals, you will find the unit hidden behind a carpeted panel at the bottom of the passenger footwell. Same place as the Engine MBE ECU.
